Tricky to find a place under the hood for it, but found one I did and it's working great. Very loud and urgent, but not irritating.
Used AWG12 wire for the power along with a 20A fuse. Wires were pushed through the firewall via a hole made in the grommet near the clutch fluid reseviour.

Fitted exactly as instructions. Over 60 mph it vibrates as the bottom slot is a lose fit. Annoying. I have the PRHT and the logo cannot be seen with the roof down as it is too low on the perspex. Also, at night, it reflects oncoming car lights back into your mirror which can be distracting. Overall, not one of the best add-ons I have fitted.

I want to give this a rave review but I just can't. It has its positives; usable space, an extra plug socket and visually appealing. However, it falls short in too many ways for me to recommend it.
Perhaps the biggest annoyance is that almost immediately the magnet that holds the lid open or closed came away in moments and could be reattached, leaving me with a sliding lid when I accelerate or brake. Considering the steep price of the unit I would have hoped for better build quality.

Don't buy this it does not fit.even using oil to help it slide on it's just far too small.
Really annoyed as it damaged the leather on thecotoinal onectryong to put it back on.More German crap that's overpriced.
